Z8018010FEG

Overview

The Z8018010FEG is an 8-bit microprocessor unit from the Z180 series, manufactured by Zilog. It operates at a maximum clock speed of 10 MHz and features a single core with an 8-bit data bus width. The device utilizes a 5.0V I/O voltage and supports an operating temperature range of -40°C to +100°C (TA). It is housed in an 80-pin Quad Flat Package (QFP) designed for surface mount applications. Key integrated peripherals include two DMA channels, two UARTs, two programmable reload timers, and an MMU supporting up to 1 MB addressing.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 CPU code while offering extended instructions and enhanced performance.
• Integrates multiple system functions on-chip, including dual DMA controllers, asynchronous serial communication interfaces, and programmable timers.
• Features an expanded Memory Management Unit allowing logical 64 KB mapping into a 1 MB physical address space.
• Includes low power-down modes and three on-chip wait-state generators to optimize system efficiency.

Applications

• Embedded systems requiring Z80 compatibility with reduced component count
• Industrial control units utilizing integrated serial communication ports
• Memory-intensive applications leveraging the onboard MMU capabilities

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for specific obsolescence notices or end-of-life announcements prior to procurement. Ensure packaging specifications match design requirements for surface mount assembly processes.

Selection Notes

Select this component when legacy Z80 software compatibility is required alongside modern integration benefits. Consider the 80-pin QFP package constraints for PCB layout. Evaluate thermal management needs given the extended temperature range specification. Verify that the 10 MHz operational speed meets the timing requirements of the target application.

Part Context

This part belongs to the Z80180 family, which extends the classic Z80 architecture with significant peripheral integration. The Z180 series was designed to reduce system costs by incorporating memory controllers, timers, and serial interfaces directly onto the silicon die. This specific variant represents the high-speed 10 MHz version within the commercial/extended temperature grade offerings.
